    • Sounds great
Packaging wasn’t great as one of the hangers poked through the box and it wasn’t taped closed very well. Installation was very easy. Hardest part was getting old muffler out of the rubber hangers. Overall time about 30 minutes. It’s not too loud as others have said with the throaty sound. I bought the clamp as well which I’m glad I did. Looks great, fits perfect and would buy again. May get some tips for it to finish the look. My check engine light came on after initial start but, did turn off after driving a bit. ... show more

    • Great fit
Great fit and sound. Just stop putting stickers on it. Couldn’t get them off so I had to run it. They burnt off and the smell was bad.

    • sounds good but a little crooked. 2015 JKU
I installed it today. It does not come with instructions but if you can't figure out how it installs, you probably should not be working on your Jeep. It's really easy to figure out how it goes. Getting hangers of was a pain but not horrible. The job took about 30 minutes. It doesn't come with a clamp and I wish the description would have told me I needed to buy one. I had the old exhaust off and realized there was no clamp. I was not fighting those hangers again so I took a dremel to the spot weld on the existing clamp and a couple taps with the claw of my hammer, it popped off. I used the old clamp and it worked fine. It sounds pretty good for a six cylinder. There is the drone at 1800-2100 rims but it is not that noticeable especially given how noisey this rattle trap jeep is. I took one star of because it's crooked, not horrible but the right pipe hangs lower. I will have to put tips or something because it will bother me. All in all, it's 114.00, so I did not expect much. Sounds good for now and wasn't hard to install. Buy a clamp when you buy the exhaust and you will be set. ... show more

    • Sounds ok but good results
Installed on a jku a litte bit more base over stock dont sound terrible purpose of purchase was to open the exhaust up and get better throttle response which it did combined with cold air intake. Only reason for 3 star rating was because the mufler was not shipped in a box. Ends of pipe was wrapped and cardboard wrapped around mufler its self it did have dents and dings but is not goin to seen since its under the jeep. But inlet pipe was not true wheather from shipping or factory defect I had to stretch it out to fit existing pipe does not come with a clamp!! ... show more

    • Well worth it!
Ok, if your are a true jeep owner, you never are finished with the add-ons (Just Empty Every Pocket). This is one item that I truely suggest for 2011 models and any other models it may fit. The price is outstanding. The install was about 30mins. The sound...... very rhythmic and smooth with a dash of you hear me coming (so move). The performance seems like you are in another vehicle. I have put an air intake about two months ago and why I did not just both at the same time is now beyond me. If you done one, do the other asap! Again, the price is very affordable. I do have to let you know..... if you have a soft top (like me) the interior sound will be very loud. Lastly, Amazon is amazing! I paid for the one day shipping and it seemed as though I got it less than a day. I have said it before and I say it again, Amazon needs a retail store! *lllllll* ... show more

    • Performs like a flowmaster. Direct replacment.
Does work and it stalled perfectly. It is louder than stock, but not extremely loud, and flow is much better if thats all you care about. It does drone irritatingly bad at steady speed with no resonator in my 2007 jeep wrangler jku. Just 2 months after installing it was covered in rust. There is 0 rust protection. I dont expect this to hold up very long at all. ... show more
